4 SHEETS-SHEET 4.- :F1 :z5- E v /f f- Gl/@Vcneodao atto/cmg operators seat, said seat being here shown as being secured to the front pair of standsteering cords 23 which are connected at their rear ends to the rear end of the plane and pass therefrom through suitable guide pulleys arranged in the frames 19 and 13 and thence extend downwardly and are connected to the opposite ends of an operating lever 24 which is pivotally mounted intermediate its ends in one side of the car frame as shown. Bythus connecting the vertical plane'with the lever it will be readily seen that when said lever is pushed downwardly the steering plane will be swung around in one direction and when the lever is pulled upwardly the plane will be swung around in the 'opposite direction thereby steering the machine at Vthe willof the operator. The horizontally disposed steering or raising and lowering plane 22 isada ted to be swung upwardly and downwar ly in a vertical plane to direct the upward and downwardcourse of the machine by operating cords 25` whichare connected attheir outer ends to the upper and lower sides of the plane near its free edge and thence extend upwardly and downwardly and are passed through suitable guide pulleys whence the extend laterally tothe opposite sides of t e frame 19 and around guide pulleys, thence downwardly along the opposite sides of the frame.

19 to the forward side of the frame 13 where they are passed through guide ulleys and extend inwardly and downwar 1y and are connected at their lower ends to the opposite ends of an operating lever 26 which is pivotally mounted intermediate its ends on the opposite side of the car` frame from the lever 24. By thus connecting the horizontal steering plane with the lever,k 26 said` plane may be tilted 'upwardly or downwardly by raising or lowering the lever 26 thereby providing for controlling the up .ward and downward movement of the machine. a suitable position in theforward portion of the car frame 13 and within convenient reach 'ofthe levers 24 and 26 is an ards 4 and arran ed between laterally and upwardly incline brace bars V27 forming part of the car frame.

The main 'plane frame 13 is suit-ably strengthened and braced by trus brace rodsy 28 which are secured at their opposite ends to the opposite ends of the frame 13 and are engaged with downwardly projecting truss pins arranged on thelower portion of the frame 13 as shown. In the endso the frame 18 between the upper and lower main planes are hingedly secured ailerons 29, said ailerons beingv pivotally connected at their forward edges to the supporting-bars .of'the frame 13thus permitting their free ends to swing upwardly or downwardl The ailerons are'automatically operated by means. of a cord 30the oppositel ends of which.' are secured to the lower portion of the car frame. The cord passes from the car frame to the end of the frame 13, is then carried upwardly through an opening formed in the lower plane. From thence the cord passes over pulleys at the bottom and top of the frame and is carrieddown 'and attached to the free edge of the aileron at that side of themachine after which it Ais carried under a pulley, across the entire width of the fra-me where it is similarly ariV ranged and secured to the, aileron on the other side of the machine and continued back to the car frame. By ythus connecting the ailerons with thetruck or car frame it will be readily seen that if the planes or car should'frock in either direction that the movement of the truck to which the ends of the aileron operating cord is attached will be imparted to the allerons'thus rocking the same in the 'pro er direction to cause the machine to quickly right itself, said ailerons thus acting, automatically to maintain the equilibrium of the machine when moving in changingg'air currents.

In order to yieldingly support the main plane frame in a horizontal position on the car frame when thev machine is still or on the ground, I rovide a su ortin s rin 31 which is herld shown'andrisp prefegialily the yform of or comprises a "flat resilient pitite or blade 32- which is secured midway tween its ends in the-upper portion of site ends to the -oppositebars of the mam the car frame and is connected at its oppoplane -irame by being slidably vengaged in openings therein whereby the `latter vis yieldingly held against tilting `when the machine is not in flight.

yFrom the foregoing description taken in laterally connection with the accompanying drawings, the 'construction and operation of the invention will be readily understood without re uiringga more extended explanation.

arious changes in the form, proportion and the minor details of construction may be `resorted to without departing from the -with and projecting forwardly from the said plane carrying frame, a brace extending between the car frame and the head plane frame and loosely connected. to the the car frame, a propeller shaft revoerated propeller, ailerons arranged in said same, a tail plane projecting rearwardly rom the main plane frame, steering planes mounted on the tail plane frame, operating levers, operating cords to connect said steering planes lwith said levers whereby 'said planes are swung in the desiredvdirection for steering the machine, a Asuitablyopmain plane frame at the ends thereof, and means to connect said ailerons with the car frame for joint action. Y

2. An aeroplane comprising awheeled car frame, a main plane frame pivotally mounted on said car frame, mai-n planes arranged on said frame above and below the pivots thereof, a forwardly projecting head plane frame rigid withsaid main frame, ahead plane arranged therein, va rearwardly projecting tail plane'frame, upper and lower tail planes arranged therein, a vertical steering plane pivotally mounted between said tail planes, a horizontal steering plane, operating levers, operatingcords to connect `said steering planes with said levers whereby said planes are swung in the" desired direction for steering the machlne, a suitably operated propeller, ailerons pivoted at their forward edges between the ends of the frames, and a cord to connect therear edges'of said ailerons with the bottom of the carA frame, said cord being connected at its v ends to the bot-tom of the car frame and operatingcords to connect said steering planes with said levers, whereby said planes lare swung in the desired direction for steering the machine, a suitably operated propeller, ailerons arranged in said main plane trame at. the ends vof the same', .and means toconnect said ailerons with the car frame whereby said ailerons will be automatically operated when the machine is tilted.

.4. An aeroplane comprising a car frame, a longitudinal sleeve secured in the upper end of the car frame, a propeller shaft revolubly mounted in saidl sleeve, means on the car frame for operating said shaft, a plane carrying frame pivoted `on said sleeve and extending above and below the same, planes secured to -the upper and lower sides. of said frame, a head plane frame rigid with and project-ing forwardly from the said. planeV carrying frame, a brace extending between the car frame and the head plane -frame and loosely connected to the same,

steering devices mounted on the plane carrylng frame, and means on the car frame to operate said devices.

5. An aeroplane comprising a wheeled car frame, a main plane frame pivotally mount- .ed on said car frame, main planes arranged on said frame, above and below the pivots thereof, a forwardly projectinghead plane frame rigid with said main frame, a head plane arranged therein, a rearwardly projee-ting tail plane frame, upper and lower tailplanes arranged therein, a vertical steering plane pivotally mounted between said tail planes, a horizontal steering plane, operating levers, operating cords to connect said steering planes with said levers whereby said planes are swung in the desired drection for steering the machine, a suitably `operated propeller, `ailerons arrangedin .said main plane frame atthe ends of the same, and means to connect said ailerons with the car frame whereby said ailerons will be automatically operatedlwhen the I na chine is tilted.

6. In an aeroplane, a car vframe, a lane frame pivotally mounted on the car rame and comprising bars having openings therein, and a plate spring centrally secured in the car lframe and having its ends slightly engaged in the openings in the frame bars for yieldingly maintaining the normal relative positions of the car frame andplane frame.

AIn testimony whereof I have hereunto set my, hand in presence of two subscribing witnesses.
